Abstract

The invention concerns a process for obtaining credits for the emission of greenhouse gases produced by the circulation of a vehicle powered by a heat engine, in which:

• • in a first stage, means are identified that can contribute towards a variation of the greenhouse gas emissions produced due to the circulation of the vehicle,
  • in a second stage, the relation establishing that variation is determined,
  • in a third stage, a certifying body guarantees the variation of the greenhouse gas emissions produced due to the circulation of the vehicle and related to the said means,
  • in a fourth stage, an organization determines the attributable greenhouse gas emission credit.

Claims

1. Process for using improved tire rolling resistance of a subject vehicle tire to obtain credits for a contribution in greenhouse gas emission variation produced by heat engine powered vehicle circulation, comprising:

A. determining the rolling resistance of the subject vehicle tire;

B. determining the rolling resistance of a reference vehicle tire;

C. calculating a reduction in the rolling resistance of the subject vehicle tire compared to that of the reference vehicle tire;

D. operating the vehicle with each tire thereon being the subject vehicle tire and measuring the greenhouse gas emissions produced during such operation;

E. operating the vehicle with each tire thereon being the reference vehicle tire and measuring the greenhouse gas emissions produced during such operation;

F. determining that a variation in greenhouse gas emission is produced by the reduction in rolling resistance during step D as compared to step E;

G. certifying the variation determined in step F; and

H. determining a greenhouse gas emission credit attributable to the certified variation.
